  • Method for preparing superabsorbent polymer
    Patent number: 10450428
    Abstract: The present invention relates to a method for preparing superabsorbent polymer. According to the preparation method of the present invention, by maintaining the hydrophilicity of superabsorbent polymer and appropriately controlling the crosslinking density, superabsorbent polymer with excellent properties can be prepared though homogeneous surface crosslinking. Thus, superabsorbent polymer with improved absorption speed can be provided without decrease in absorbency under load.
    Type: Grant
